| 摘 要： | 采用脂肪族环氧树脂(EP-664)与丙烯酸(AA)合成了低黏度的含有环氧基的丙烯酸酯(AEG),该反应性酯类化合物与双酚A型环氧树脂(E-44、EP-6002)共混,以甲基六氢苯酐(MeHHPA)为固化剂,并分别采用三级胺和2-乙基-4-甲基咪唑(2E4MZ)为促进剂,通过混合物黏度曲线的变化与其固化物力学性能的测试,研究了AEG含量对环氧树脂体系黏度的变化和固化物力学性能的影响。结果显示,AEG的添加可以有效地降低树脂体系的黏度,25℃下混合体系黏度仅为300～600mPa·s;其固化物的力学性能随AEG含量的增加先增加后降低,具有最大值。三级胺固化体系的力学性能明显优于2E4MZ固化体系,当w(AEG)为20%时,固化物的综合力学性能最好。

| Abstract: | An acrylate with an epoxy group(AEG) having low viscosity was synthesized by the reaction of aliphatic epoxy resin(EP-664) and acrylic acid(AA).The AEG mixed with the blend of two epoxy resins(E-44 and EP-6002),and then the resulting mixture was cured with MeHHPA when a tertiary amine and 2-ethyl-4- methylimidazole(2E4MZ) was respectively used as an accelerating agent.The effect of AEG content on the viscosity of the epoxy resin cured system was studied by viscosity curves,and the mechanical properties of t... |
